Fig. 1B is a schematic plan view of an electronic device according to another embodiment of the present application. Fig. 1C is a schematic side view of an electronic device according to yet another embodiment of the present application. As shown in fig. 1A to 1C, the electronic apparatus includes:

camera module 110, display screen 120 and photosensitive device 130.

It should be understood that the Display 120 herein includes, but is not limited to, a self-luminous Display such as an Organic Light-Emitting Display (OLED) or a Liquid Crystal Display (LCD), and the embodiment of the present application is not limited thereto.

The display screen 120 may include a light transmissive cover plate 122, a luminescent layer 124, and a black glue layer 126. As shown in fig. 1C, the display screen 120 may be sequentially provided with a light-transmitting cover plate 122, a light-emitting layer 124 and a black glue layer 126 in a top-to-bottom direction. The transparent cover 122 includes, but is not limited to, a glass cover, a cover made of Polyimide (PI), and the like.

It should also be understood that the Camera Module (CCM) 110 may include a lens, an imaging chip, a circuit board such as a flexible circuit board, and an image processing chip (or a signal processing unit).

It is also understood that the photosensitive device 130 may include a photosensitive element, which may have a photosensitive surface. The light sensing device may also include other electronic components such as transistors, resistors, capacitors, and the like. The photosensitive device can be used for forming an ambient light sensor to realize detection of ambient light signals, can also be used for forming an optical proximity sensor to realize proximity detection, and can also realize detection of the ambient light signals and detection of human body proximity light signals at the same time.

The display screen 120 includes a light-transmissive opening 121. The camera module 110 includes a lens barrel 111. The lens barrel 111 has a light inlet 112, and the light inlet 112 is capable of receiving the first portion of light transmitted through the light-transmitting opening 121.

In one example, for a self-luminous display screen, an opening process may be performed on a black glue layer of the display screen, and an opening or light transmission process may be performed on a light emitting layer to form a light transmission opening. In another example, the lcd may include a backlight module that does not transmit light, and for the lcd, an opening may be provided to the backlight module to form a light-transmitting opening.

The light sensing device 130 is disposed on a side of the lens barrel 111 facing the display screen 120.

The light sensing device 130 includes a light transmitting area 131 and a light sensing area 132, the light transmitting area 131 is used for transmitting a first portion of light passing through the light transmitting opening 121 and being incident on the light inlet 112, and the light sensing area 132 is used for receiving and sensing a second portion of light passing through the light transmitting opening 121.

Specifically, the lens barrel of the camera module 110 may be located below the display screen 120, and the lens barrel 111 of the camera module 110 is disposed below the opening of the black glue layer 126 below the light-transmitting cover plate 122. The light sensing device 130 is located below the display screen 120 and above the camera module 110, in other words, the light sensing device 130 is disposed above the lens barrel 111.

It should also be understood that in the present application, the electrical signal generated by the light sensing device needs to be processed by the signal processing unit. The signal processing unit may be located on the photosensitive device, or located at a circuit board of the camera module, or located at the main circuit board 140 of the electronic device. For example, the light sensing device 130 is connected to the main circuit board 140 through the circuit board 150.

As shown in fig. 1A, the lens barrel 111 has a light inlet 112, for example, the light inlet 112 may be defined by an inner wall of one end (upper end) of the lens barrel 111 facing the display screen 120. As shown in fig. 1B, the camera module 110 is disposed below the light-transmitting opening of the display screen 120. As shown in fig. 1C, the external light can enter the light inlet 112 of the camera module 110 through the light inlet 121, and then reaches the photoelectric converter 119 through the lens 118 disposed in the camera module 110 to generate an electrical signal, which is transmitted out through the circuit board after being processed, so as to realize the function of the camera module.

As an example, as shown in fig. 1C, the photosensitive device 130 is located above the lens barrel 111 of the camera module 110, and the center of the photosensitive device 130 may be formed as a light-transmitting region. In the present embodiment, the light-transmitting area corresponds to the light inlet 112 of the camera module 110. It should be understood that the light-transmitting region may be adapted to the light inlet of the camera module, or alternatively, may be defined by the size and shape of the light inlet, which may be of any shape. The photosensitive region of the photosensitive device may be located at a periphery of the light-transmitting region and not overlap with the light-transmitting region. As an example, the light-transmitting region may be circular and the light-sensing region may be annular.

In the scheme of this application embodiment, the first part light through the light-admitting entrance can see through and incide to the light-admitting entrance to the sensitization region is used for receiving and the sensing sees through the second part light of light-admitting entrance, consequently utilizes the light-admitting entrance that the camera module corresponds to realize the effective sensing of external light, has avoided setting up the opening to the display screen alone to the sensitization device, has guaranteed the continuity of display screen.

Further, the lens barrel 111 may have a size smaller than that of the light transmission opening 121. The lens barrel 111 may also have a size larger than the light transmission opening 121. Preferably, because the demand of assembly, the light inlet size on the display screen is slightly greater than the region of the light inlet of camera module usually, namely, the region of the light inlet of display screen can be greater than the region of the light inlet of camera module, can guarantee like this that light enters into the camera module via the light inlet smoothly, but, if the light inlet is too big will influence the screen of display screen to account for than. In the scheme of this application embodiment, because photosensitive device sets up in the one side of the orientation display screen of lens cone, make full use of the printing opacity scope of the printing opacity mouth of display screen, avoided because the printing opacity mouth of display screen sets up too big and sacrifice the screen of display screen and account for the ratio, in other words, guaranteed the screen of display screen and accounted for the ratio.

For example, in the case where the photosensitive device is disposed around the lens barrel, the light-transmitting opening needs to be set larger if effective sensing of the outside light is to be ensured. In this application embodiment, the sensitization device sets up in the one side of the orientation display screen of lens cone, need not to set to bigger printing opacity mouth specially to the sensitization device, has consequently guaranteed the screen of display screen to account for than better.

In one example, the light-transmitting opening can be adapted to the outer edge of the lens barrel, and the size of the light-transmitting opening does not need to be specially set for the photosensitive device, in other words, the light-transmitting opening only needs to be set for the size of the lens barrel of the camera module, so that backward compatibility of the display screen is realized, and the screen occupation ratio of the display screen is guaranteed to the maximum extent.

In addition, the sensitization device sets up in the one side of the orientation display screen of lens cone, and the first part light through light-transmitting opening can see through and incide to the light inlet of camera module, and consequently, the influence of sensitization device to the formation of image of camera module has been avoided to this kind of mode of setting up.

In addition, the light sensing area is used for receiving and sensing the second part of light penetrating through the light transmission opening, so that the influence of the light from the self-luminous layer of the display screen is avoided, and the light detection effect is guaranteed. For example, when the photosensitive device is used for detecting ambient light, the arrangement mode greatly reduces the influence of self-luminescence of the screen, prevents the ambient light detection result from generating large errors due to the fact that the photosensitive device cannot distinguish whether the received light is the ambient light or the self-luminescence of the screen, and accordingly improves the accuracy of the ambient light detection.

The light transmissive region may not be part of the entity of the photosensitive device, for example, the light transmissive region may be a hollow region surrounded by the photosensitive region.

Specifically, as shown in fig. 2A, a schematic plan view of a photosensitive device provided in an embodiment of the present application is shown. The photosensitive area of the photosensitive device 130 is annular, the inner side of the annular is the light inlet 112 (inner wall of the lens barrel), and the outer side of the annular is the outer wall of the lens barrel 111. In the schematic plan view shown in fig. 2, a rectangular barrel base 113 of the barrel 111 is also shown.

In one example, when the Light-sensing region is composed of an amorphous silicon (amorphous silicon) photodiode (LED) or an Organic photodiode (OLED), a Light-sensing device may be formed on a transparent substrate (e.g., a glass substrate, a Polyimide (PI) substrate, etc.) to form the Light-sensing region, and a region where no element such as a Light-sensing element is formed may be used as the Light-transmitting region.

In another example, when the photosensitive region is comprised of a single crystal silicon photodiode, it can be fabricated directly on a single crystal silicon substrate to form a photosensitive device. For example, a process such as etching, laser cutting, etc. may be used to cut out a portion of the region to form a light-transmitting region, and the remaining non-cut out region may be used as a photosensitive region.

As one example, the light-transmitting area is circular and the light-sensing area is annular. Since the light-transmitting area is circular and the light-sensing area is annular, the shape of the light-transmitting area is matched with that of the light inlet of the lens barrel, light received by the light inlet of the lens barrel cannot be influenced, and therefore imaging of the camera module cannot be influenced, and fig. 2B shows a schematic diagram of the light-sensing device of the example. As shown in fig. 2B, the light sensing device 130 includes a light sensing region 131 and a light transmission region 132, and is connected with a circuit board 250. In one example, the circuit board 250 may be a flexible circuit board.

In another implementation of the present application, the photosensitive region surrounds the light-transmissive region, and an inner edge of the photosensitive region coincides with an outer edge of the light-transmissive region. Such mode of setting up can guarantee well that first part light can be incited into the light inlet of camera module via the light-transmitting area of sensitization device, does not influence the formation of image of camera module.

In another implementation of the present application, an outer edge of the photosensitive region coincides with an outer edge of the lens barrel. Such a mode of setting up neither influences the formation of image of camera module, also need not enlarge the size of printing opacity mouth in order to make the photosensing device can fully receive the light signal who sees through the printing opacity mouth of display screen, is favorable to improving the screen and accounts for the ratio.

In another implementation of the present application, the photosensitive region includes a plurality of filter regions alternately disposed along a periphery of the light-transmitting region, and adjacent filter regions of the plurality of filter regions have different filter bands.

Specifically, the light sensing device in the electronic device in the present application is used for detecting light from the outside through the cover plate. For example, ambient light may be used. The photosensitive device can convert incident ambient light into an electric signal, and further can calculate the intensity of the ambient light. Further, the photosensitive device may be divided into a plurality of areas, with different areas covered with different filters.

In another implementation of the present application, the different filtering bands include three visible bands. In particular, the filter region may be implemented as an optical filter. The photosensitive device as an example may be covered with three kinds of monochromatic filters of red (R), green (G), and blue (B). The signals generated by the light sensing devices under the different monochromatic filters can be used to provide color temperature information for the ambient light source. Fig. 2C shows a schematic view of a photosensitive region as this example.

In addition, the different filtering bands may include a visible light band and an infrared band to improve reliability of the visible light band and the infrared band. Specifically, the photosensitive device may be covered with a visible light filter and an infrared filter. For example, the infrared filter may transmit light at 940nm, such that the light sensing device may detect infrared light signals emitted by the electronic device. Further, the visible light signal transmitted through the visible light filter can be used for realizing ambient light detection, and the infrared light signal transmitted through the infrared light filter can be used for judging a proximity signal of a human body and also can be used for judging a gesture change signal of the human body. Fig. 2D shows a schematic view of a photosensitive region as this example.

In another implementation manner of the present application, the light-transmitting area is circular, and the photosensitive area is located at a connection position between the rectangular circuit board of the photosensitive device and the photosensitive device. The arrangement mode enables the space of the photosensitive area to be effectively utilized, and the detection reliability of the photosensitive area is improved.

Fig. 3A shows a schematic view of a photosensitive region as this example. As shown, the light sensing device 130 includes a light sensing region 131 and a light transmission region 132, and a flexible circuit board 350 is connected thereto. Fig. 3B shows a side view schematic of the electronic device of this example.

In another implementation manner of the present application, the photosensitive device is electrically connected to a main circuit board of the electronic device through the first flexible circuit board. Such a wiring manner allows the flexibility of the positional relationship between the photosensitive device and the main circuit board to be improved.

In another implementation manner of the present application, the camera module is electrically connected to a main circuit board of the electronic device through a second flexible circuit board. The wiring mode improves the flexibility of the position relation between the camera module and the main circuit board.

In another implementation of the present application, the photosensitive device is electrically connected to a circuit board of the camera module. The wiring mode enables wiring between the circuit board of the camera module and the main circuit board not to be changed, and wiring difficulty is reduced.

In another implementation of the present application, the photosensitive device is electrically connected to the circuit board of the camera module through the flexible circuit board. The wiring mode improves the flexibility of the position relation between the camera module and the photosensitive device.

In another implementation of the present application, the photosensitive device is electrically connected to the circuit board of the camera module through the internal wiring of the barrel wall of the lens barrel. Such a wiring manner allows a space occupied by the wiring in the electronic device to be reduced.

In another implementation of the present application, a display screen is provided with a light emitting layer, wherein the light emitting layer has a first opening forming a light transmissive opening. The arrangement mode effectively avoids the shielding of the luminescent layer to the external light.

In another implementation of this application, the display screen is provided with the luminescent layer, and the luminescent layer includes first luminescent region and second luminescent region, and the luminousness of first luminescent region is less than the luminousness of second luminescent region, and the second luminescent region is used for forming the printing opacity mouth.

Because the luminousness of first luminous zone is less than the luminousness of second luminous zone, consequently avoided the sheltering from of luminescent layer to external light effectively to because the second luminous zone also has the display function, thereby guaranteed the display effect of display screen.

In another implementation of the present application, a black glue layer is provided to the display screen, wherein the black glue layer has a second opening forming a light transmissive opening. The arrangement mode effectively avoids the shielding of the black glue layer on the external light.

In another implementation of the present application, a portion of the photosensitive device is covered by the non-opening portion of the black glue layer. In other words, a portion of the photosensitive region senses the first portion of the light through the second opening, and another portion of the photosensitive region is blocked by the non-opening portion outside the second opening of the black glue layer.

Because one part of the photosensitive area senses the first part of light through the second opening and the other part of the photosensitive area is shielded by the non-opening part of the black glue layer, the space corresponding to the light-transmitting area is fully utilized to increase the area of the photosensitive area.

Fig. 4 is a schematic diagram showing a connection manner of the flexible circuit board according to another embodiment. The electronic device of fig. 4 includes:

display screen 420, camera module 410 and photosensitive device 430.

The camera module 410 includes a lens barrel 411, and a light inlet 412 of the lens barrel is used for receiving a first portion of light passing through a light-transmitting opening 421 of the display 420.

The light sensing device 430 is disposed on a side of the lens barrel 411 facing the display 420, and is configured to sense a second portion of light passing through the light-transmitting opening 421.

As shown in fig. 4, the photosensitive device 430 may be electrically connected to the main circuit board 440 through a first flexible circuit board, and the circuit board of the camera module may be electrically connected to the main circuit board 440 through a second flexible circuit board. In other words, the electrical signal generated by the light sensing device is directly connected to the main circuit board of the electronic device via a flexible circuit board. The electric signal of the camera module is connected to the other side of the main circuit board through another flexible circuit board.

In addition, the light sensing device in the embodiment of the present application can realize ambient light detection or infrared optical proximity sensing. As shown in fig. 4, in this example, the electronic device includes a display screen 420 and a back plate 490. The display screen 420 may include a light transmissive cover plate 422, a light emitting layer 424, and a black glue layer 426. A small hole may be provided near the bezel 480 of the electronic device. A light guide structure 460 is located in the aperture. The electronic device also has an infrared light source 470 that emits light at 940 nm. The light guide structure 460 is used to guide the infrared light from the infrared light source out of the light-transmissive cover 422. The photosensitive device may be provided with both an infrared-transmitting filter and at least one visible light filter. The infrared light emitted by the infrared light source can be received by the photosensitive device after being emitted by a human body.

Specifically, the flexible circuit board can transmit the electric signal generated by the photosensitive device to the circuit board of the camera module. Fig. 5A shows a schematic diagram of a connection manner of the flexible circuit board of the present example. As shown, the light sensing device 430 is connected to a circuit board of the camera module through a flexible circuit board 551.

Specifically, in the process of manufacturing the lens barrel of the camera module, some metal wires penetrating up and down are manufactured inside the lens barrel. For example, the manufacturing method may be heterogeneous multi-material injection molding. The circuit board of sensitization device and camera module is connected at the metal wire both ends in the camera module lens cone, can be with the signal of telecommunication connection that produces on the sensitization device to the circuit board of camera module.

Fig. 5B shows a schematic diagram of a connection manner of the flexible circuit board of the present example. As shown, the camera module 410 includes a lens barrel, and an internal wiring 552 of a barrel wall of the lens barrel is electrically connected to the photosensitive device.

Fig. 6A is a schematic side view of an electronic device according to another embodiment of the present application. The electronic device of fig. 6A includes:

display screen 620, camera module 610 and photosensitive device 630.

The camera module 610 includes a lens barrel, and a light inlet of the lens barrel is used for receiving a first portion of light passing through a light-transmitting opening 621 of the display screen 620.

The light sensing device 630 is disposed on a side of the lens barrel facing the display screen 620, and is used for sensing the second part of light passing through the light transmitting hole 621.

As shown, the display screen may be provided with a black glue layer 626. The black adhesive layer 626 has an opening 6261 forming a light transmission opening. The arrangement mode effectively avoids the shielding of the black glue layer on the external light.

In one example, the display 626 is provided with a light emitting layer 624. The light-emitting layer 624 has an opening 6240 forming a light-transmitting opening. The arrangement mode effectively avoids the shielding of the luminescent layer to the external light. It will be appreciated that both the first opening and the second opening may be adapted to the light transmissive opening of the display screen. Preferably, the second opening is aligned with the first opening.

Further, fig. 6B shows a side view schematic of another example electronic device. The light emitting layer 624 includes a first light emitting region 6241 and a second light emitting region 6242, the light transmittance of the first light emitting region 6241 is smaller than that of the second light emitting region 6242, and the second light emitting region 6242 is used to form a light transmission opening. It is understood that the second light emitting zone 6242 can be machined in alignment with the opening 6241.

Because the light transmittance of the first light-emitting area is smaller than that of the second light-emitting area, the light-emitting layer is effectively prevented from shielding external light. In addition, the second light-emitting area has a display function, so that the arrangement mode can improve the display effect of the display screen.

Specifically, in some example electronic devices, the light-emitting layer of the display screen is not provided with an opening, but only an opening is provided in the black glue layer, so that external light can enter the camera module through the second light-emitting layer. Due to the arrangement mode, the picture can be displayed at the area of the display screen corresponding to the position above the camera module.

It is to be understood that the first light-emitting layer and the second light-emitting layer both belong to the same light-emitting layer. The light transmittance of the first light-emitting area is smaller than that of the second light-emitting area, for example, the density of light-emitting point electronic elements in the second light-emitting area can be significantly lower than that of light-emitting electronic elements in the first light-emitting area, and the arrangement mode can reduce the influence caused by the size of the opening of the display screen, so that the screen occupation ratio of the display screen is further improved.

In addition, it should be understood that the present application is equally applicable to electronic devices having a camera on the back side. When being equipped with transparent apron or transparent backplate on electronic equipment's the camera module, this application all can be applicable to opening size and the opening proportion that reduces panel or backplate.

In addition, fig. 6C is a schematic side view of another exemplary electronic device, as shown, a portion of the photosensitive region senses a first portion of light through the second opening, and another portion of the photosensitive region is blocked by the non-opening portion of the black glue layer 626. The arrangement mode makes full use of the space corresponding to the light transmission area to increase the area of the light sensing area.
